Objective: To investigate temporal changes in structural progression assessed by serial conventional radiography and magnetic resonance imaging (MRI) of the sacroiliac joints (SIJs) and spine in patients with ankylosing spondylitis (AS) treated with tumour necrosis factor (TNF) inhibitor for 5 years.Method: Forty-two patients were included and 33 patients were followed for 5 years in a prospective investigator-initiated study. Conventional radiographs were required four times and MRI seven times. The modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS); Spondyloarthritis Research Consortium of Canada (SPARCC) MRI SIJ and Spine Inflammation, and SPARCC MRI SIJ Structural Score (SSS) for Fat, Erosion, Backfill, and Ankylosis; and the Canada-Denmark MRI scores for Spine Inflammation, Fat, Erosion, and New Bone Formation (NBF) were applied.Results: Compared with baseline, MRI Inflammation had decreased significantly at week 22 (spine)/week 46 (SIJ) and thereafter. MRI SIJ Fat (from week 22), SIJ Ankylosis, Spine NBF, and mSASSS had increased significantly at week 46 and thereafter. SIJ Erosion had decreased from year 2. The annual progression rate in mSASSS was significantly higher during weeks 0-46 compared to week 46 to year 3. In multivariate regression analyses, baseline SIJ Inflammation and Backfill were independent predictors of 5 year progression in SIJ Ankylosis. Spine Erosion predicted progression in Spine NBF. Longitudinally, Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index, MRI Spine Inflammation, Fat, and Erosion scores were significantly associated with mSASSS. SIJ Inflammation, Fat, Erosion, and Backfill scores were longitudinally associated with SIJ Ankylosis. Structural progression was not associated with body mass index, smoking, or Assessment of SpondyloArthritis international Society Non-Steroidal Anti-Inflammatory Drug Index.Conclusion: In a 5 year follow-up study of patients with AS treated with TNF inhibitor, structural progression decreased over time.

Objectives: To evaluate participant-reported atypical dysphagia symptoms and their association with oxaliplatin treatment., Methods: This observational study recruited 73 adults with solid tumours outside the head, neck or upper gastrointestinal tract. All had dysphagia, were in hospital or hospice and were treated by Medical Oncology, Radiation Oncology or Palliative Care. Participants reported their experiences of swallowing difficulties by semistructured interview. Oral Health Assessment Tool was used to ensure swallow difficulties were not due to mucositis. Responses were transcribed and analysed by content analysis. Atypical difficulties were examined for association with oxaliplatin treatment by Fischer's Exact., Results: Oxaliplatin treatment was associated with three unusual dysphagia symptoms: problems with cold or hot bolus (p=0.01), pins and needles (p=0.001) and throat spasm (p=0.035). Carbonation was problematic for one participant. Chemotherapy commencement coincided with swallow problem onset for 67%. Dysphagia symptoms were unrelated to mucositis (p=0.165)., Conclusions: Swallowing difficulties in oxaliplatin-treated patients are atypical and attributable to chemotherapy commencement. Previous research suggests that dysphagia is triggered by cold exposure, but hot and carbonated boluses also caused problems here. Dysphagia symptoms and triggers should be studied more fully to help patients safely enjoy their meals and prevent food avoidance, which could exacerbate malnutrition., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Context: Dysphagia is common in cancer, but underlying pathophysiology and manifestations within patients are unknown., Objectives: To examine dysphagia characteristics in those with solid malignancies outside the head, neck and upper gastrointestinal tract., Methods: Seventy-three individuals with dysphagia (46 male, 27 female, aged 37-91) were recruited from a parent trial conducted in two acute hospitals and one hospice. Cranial nerve function, Oral Health Assessment Tool (OHAT), Mann Assessment of Swallowing Ability (MASA) and Functional Oral Intake Scale (FOIS) evaluated swallow profile., Results: Only 9/73 (12%) had documented dysphagia prior to study enrollment. MASA risk ratings found n=61/73 (84%) with dysphagia risk and n=22/73 (30%) with aspiration risk. Food texture modification was required for n=34/73 (47%), fluid texture modification for n=1/73 (1%). Compensatory strategies for food were needed by n=13/73 (18%) and for fluids by n=24/73 (33%). Cranial nerve deficits were present in n=43/73 (59%). Oral health problems were common, with xerostomia in two-thirds. Worse dysphagia on MASA was associated with disease progression, affecting hospice, and palliative care the most. Worse performance status was indicative of poorer MASA raw score (P<0.001, OR 2.2, 95% CI 1.5-3.4), greater risk of aspiration (P=0.005, OR 2.1, 95% CI 1.3-3.6) and lower FOIS (P=0.004, OR 2.0, 95% CI 1.2-3.2)., Conclusion: Dysphagia management in those with cancer requires robust assessment to uncover clinically important needs like food texture modification and safe swallowing advice. Better assessment tools should be developed for this purpose. Oral health problems should be routinely screened in this population since they exacerbate dysphagia., (Copyright © 2022 The Authors.

Objectives: Emerging evidence supports exercise as a therapeutic intervention for patients with bone metastases. However, exercise prescription in practice is limited by concerns regarding skeletal-related events (SREs). This study examined associations among habitual physical activity levels, history of SREs, and patient reported outcomes in patients with bone metastases., Data Sources: A total of 58 patients with bone metastases (n = 45 breast cancer; n = 13 prostate cancer; mean time since cancer diagnosis 5.8 [4.7] years) were assessed. Habitual physical activity levels were collected by accelerometry. Standardized subjective assessment collected history of SREs, quality of life (EORTC-QLQ-C30 and EORTC-BM22), pain (Brief Pain Inventory), sleep quality (Pittsburgh Sleep Quality Questionnaire), and perceptions about exercise (Exercise Benefits/Barriers Scale). Participants spent a mean of 77.37% (standard deviation 14.3)% of waking hours sedentary and a mean of 20.14% (standard deviation 13.4)% of waking hours in light intensity activity. Almost half (n = 28) completed ≥150 min/wk moderate-to-vigorous intensity activity. Higher levels of moderate-to-vigorous intensity activity were associated with lower pain scores, better perceived physical function, lower functional interference scores, and better quality of life. Patients with a history of fracture since diagnosis spent more time sedentary and in light intensity activity in comparison to those with no fracture history (P < .05)., Conclusion: Moderate-to-vigorous intensity physical activity may have multiple benefits for patients with bone metastases. Reducing sedentary behavior may be a key target for patients with a history of fracture., Implications for Nursing Practice: Oncology nurses play a key role in providing education on the benefits of exercise, overcoming barriers to physical activity and timely referrals., (Copyright © 2022 The Authors.

Objectives: To study if clinical, radiographic and MRI markers can predict MRI and radiographic damage progression and achievement of stringent remission in patients with established RA in clinical remission followed by a targeted treatment strategy., Methods: RA patients (DAS28-CRP <3.2, no swollen joints) receiving conventional synthetic DMARDs were randomized to conventional or MRI-targeted treat-to-target strategies with predefined algorithmic treatment escalations. Potentially predictive baseline variables were tested in multivariate logistic regression analyses., Results: In the 171 patients included, baseline MRI osteitis independently predicted progression in MRI erosion [odds ratio (OR) 1.13 (95% CI 1.06, 1.22)], joint space narrowing [OR 1.15 (95% CI 1.07, 1.24)] and combined damage [OR 1.23 (95% CI 1.13, 1.37)], while tenosynovitis independently predicted MRI erosion progression [OR 1.13 (95% CI 1.03, 1.25)]. A predictor of radiographic erosion progression was age, while gender predicted progression in joint space narrowing. Following an MRI treat-to-target strategy predicted stringent remission across all remission definitions: Clinical Disease Activity Index remission OR 2.94 (95% CI 1.25, 7.52), Simplified Disease Activity Index remission OR 2.50 (95% CI 1.01, 6.66), ACR/EULAR Boolean remission OR 5.47 (95% CI 2.33, 14.13). Similarly, low tender joint count and low patient visual analogue scale pain and global independently predicted achievement of more stringent remission., Conclusion: Baseline MRI osteitis and tenosynovitis were independent predictors of 2 year MRI damage progression in RA patients in clinical remission, while independent predictors of radiographic damage progression were age and gender. Following an MRI treat-to-target strategy, low scores of patient-reported outcomes and low tender joint count predicted achievement of stringent remission., Trial Registration: ClinicalTrials.gov (https://clinicaltrials.gov), NCT01656278., (© The Author(s) 2020.

Objective: To investigate the distribution of whole-body magnetic resonance imaging (WB-MRI) inflammatory lesions of peripheral joints and entheses, and their response to adalimumab (ADA) treatment and agreement with clinical measures of disease activity in patients with axial spondyloarthritis (axSpA)., Methods: Explorative analysis of an investigator-initiated randomized controlled trial of ADA. WB-MRI was performed at weeks 0, 6, 24, and 48. Detailed analyses of WB-MRI lesions in peripheral joints and entheses were performed, including agreement with clinical measures of disease activity., Results: WB-MRI inflammatory lesions were most frequently observed in the acromioclavicular, metatarsophalangeal, and wrist joints (> 10% of joints), and at the greater trochanter, calcaneal insertion of the Achilles tendon, and ischial tuberosity (> 15% of entheses). Inflammation resolved in ≥ 2/3 of involved sternoclavicular, metacarpophalangeal, first carpometacarpal, hip, and tarsometatarsal joints, and pubic symphyses and medial femoral condyles. In contrast, inflammation resolved in ≤ 1/6 of involved acromioclavicular joints, knee joints, and supraspinatus tendon insertions at humerus. Tenderness of joints and entheses agreed poorly with WB-MRI inflammation (κ < 0.40). Joint tenderness resolved more frequently in MRI-positive than MRI-negative joints (8/13, 62% vs 9/34, 26%) after 6 weeks of active treatment., Conclusion: Inflammatory lesions of peripheral joints and entheses in patients with predominantly axSpA, and changes therein, can be mapped using WB-MRI, and it may contribute to differentiate between inflammatory and noninflammatory joint tenderness.

Context: Dysphagia is usually associated with malignancies of the head, neck, and upper gastrointestinal tract but also occurs in those with tumors outside anatomic swallow regions. It can lead to aspiration pneumonia, malnutrition, reduced quality of life, and psychosocial distress. No studies have yet reliably described dysphagia prevalence in those with malignancies outside anatomic swallow regions., Objective: The objective of this study was to establish the prevalence and predictors of dysphagia in adults with solid malignancies outside the head, neck, and upper gastrointestinal tract., Methods: A cross-sectional, observational study using consecutive sampling was conducted. There were 385 participants (mean age 66 ± 12 years) with 21 different primary cancer sites from two acute hospitals and one hospice. Locoregional disease was present in 33%, metastatic in 67%. Dysphagia was screened by empirical questionnaire and confirmed through swallow evaluation. Demographic and clinical predictors were determined by univariate and multivariate binary regression., Results: Dysphagia occurred in 19% of those with malignancies outside anatomic swallow regions. Prevalence was 30% in palliative care and 32% in hospice care. Dysphagia was most strongly associated with cough, nausea, and worse performance status. It was also associated with lower quality of life and nutritional difficulties., Conclusion: Dysphagia was common and usually undiagnosed before study participation. It occurred at all disease stages but coincided with functional decline. It may therefore represent a cancer frailty marker. Oncology and palliative care services should routinely screen for this symptom. Timely dysphagia identification and management may improve patient well-being and prevent adverse effects like aspiration pneumonia and weight loss., (Copyright © 2019 American Academy of Hospice and Palliative Medicine.

Context: Taste and smell abnormalities (TSA) occur throughout the cancer trajectory regardless of cancer primary site and contribute to cancer-associated malnutrition. TSA etiology is poorly understood. Tumor-related inflammation is a possible cause., Objective: This study examined the prevalence, characteristics, and severity of TSA in advanced cancer and explored the relationship between TSA and nutritional status. No previous study combined subjective and objective measures for both taste and smell assessment in this population., Method: Consecutive advanced cancer hospice patients were recruited. A modified version of the "Taste and Smell Survey" assessed subjective TSA. Validated taste strips and "Sniffin' Sticks" were the objective measures. The abridged patient-generated subjective global assessment evaluated nutritional status., Results: A 93% prevalence of TSA in 30 patients with advanced cancer was identified. When subjective and objective evaluations were combined, 28 had taste abnormalities, 24 smell abnormalities, and 24 both. Taste changes included "persistent bad taste" (n = 18) and changes in how basic tastes were perceived. Half reported smell was not "as strong" as prediagnosis, while more than half (n = 16) had an objective smell abnormality. Most (97%) were at risk of malnutrition. Fatigue, dry mouth, early satiety, and anorexia were common nutrition-impact symptoms. No statistically significant relationship was found between TSA and malnutrition scores., Conclusions: TSA were highly prevalent. Subjective taste and smell changes did not always accord with objective TSA, suggesting both assessments are valuable. TSA characteristics varied, and particular foods tasted and smelled different and were not enjoyed as before. TSA are common, high-impact problems in advanced cancer.

Importance: Whether using magnetic resonance imaging (MRI) to guide treatment in patients with rheumatoid arthritis (RA) improves disease activity and slows joint damage progression is unknown., Objective: To determine whether an MRI-guided treat-to-target strategy vs a conventional clinical treat-to-target strategy improves outcomes in patients with RA in clinical remission., Design, Setting, and Participants: Two-year, randomized, multicenter trial conducted at 9 hospitals in Denmark. Two hundred patients with RA in clinical remission (disease activity score in 28 joints-C-reactive protein [DAS28-CRP] <3.2 and no swollen joints) were enrolled between April 2012 and June 2015. The final follow-up visit was April 2017., Interventions: Patients were randomly allocated (1:1) to an MRI-guided vs a conventional treat-to-target strategy. In the MRI-guided group, the treatment goal was absence of MRI bone marrow edema combined with clinical remission, defined as DAS28-CRP of 3.2 or less and no swollen joints. In the conventional group, the treatment goal was clinical remission., Main Outcomes and Measures: Co-primary outcomes were proportions of patients achieving DAS28-CRP remission (DAS28-CRP <2.6) and with no radiographic progression (no increase in total van der Heijde-modified Sharp score) at 24 months. Significance testing for the primary outcome was based on 1-sided testing. Secondary outcomes were clinical and MRI measures of disease activity, physical function, and quality of life., Results: Of 200 patients randomized (133 women [67%]; mean [SD] age, 61.6 [10.5] years; median baseline DAS28-CRP, 1.9 [interquartile range, 1.7-2.2]; van der Heijde-modified Sharp score, 18.0 [interquartile range, 7.0-42.5]), 76 patients (76%) in the MRI-guided group and 95 (95%) in the conventional group completed the study. Of these, 64 (85%) vs 83 (88%), respectively, reached the primary clinical end point (risk difference, -4.8% [1-sided 95% CI, -13.6% to + ∞; 1-sided P = .19]) and 49 (66%) vs 58 (62%), respectively, reached the primary radiographic end point (risk difference, 4.7% [1-sided 95% CI, -7.0% to + ∞; 1-sided P = .25). Of 10 key secondary end points, 8 were null and 2 showed statistically significant benefit for the MRI treat-to-target group. Seventeen patients (17%) in the MRI-guided treat-to-target group and 6 patients (6%) in the conventional treat-to-target group experienced serious adverse events., Conclusions and Relevance: Among patients with RA in clinical remission, an MRI-guided treat-to-target strategy compared with a conventional treat-to-target strategy did not result in improved disease activity remission rates or reduce radiographic progression. These findings do not support the use of an MRI-guided strategy for treating patients with RA., Trial Registration: ClinicalTrials.gov Identifier: NCT01656278.

Objective: To investigate whether adalimumab (ADA) reduces whole-body (WB-) magnetic resonance imaging (MRI) indices for inflammation in the entheses, peripheral joints, sacroiliac joints, spine, and the entire body in patients with axial spondyloarthritis (axSpA)., Methods: An investigator-initiated, randomized, placebo-controlled, double-blinded 48-week followup trial included 49 patients with axSpA, who had Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥ 4.0 despite treatment with nonsteroidal antiinflammatory drugs and a clinical indication for tumor necrosis factor inhibitor treatment. Patients were randomized to subcutaneous ADA 40 mg or placebo every other week for 6 weeks; thereafter, all patients received ADA. Conventional MRI and WBMRI were performed at weeks 0, 6, 24, and 48. The primary WBMRI endpoint was the proportion of patients with an improvement in WBMRI total inflammation index above the smallest detectable change (SDC) at Week 6., Results: The primary WBMRI endpoint (improvement of SDC > 2.3) was met in 11 (44%) patients in the ADA group and 3 (13%) patients in the placebo group (p = 0.025, Fisher's exact test). The primary conventional MRI endpoint, the minimally important change in Spondyloarthritis Research Consortium of Canada Spine MRI Inflammation Index at Week 6, was achieved by 9 (36%) patients in the ADA group and 4 (17%) patients in the placebo group (p = 0.20). The primary clinical endpoint, BASDAI reduction > 50% or 2.0 at Week 24, was attained by 32 (65%) patients., Conclusion: ADA provided significant reductions in WBMRI indices of peripheral, axial, and whole-body inflammation in patients with axSpA. WBMRI is promising for objective assessment and monitoring of peripheral and axial disease activity in future clinical trials.

Background: The Canada-Denmark (CANDEN) definitions of spinal MRI lesions allow a detailed anatomy-based evaluation of inflammatory and structural lesions in vertebral bodies and posterior elements of the spine in patients with axial spondyloarthritis (axSpA). The objective was to examine the reliability, responsiveness and discrimination of scores for spinal inflammation, fat, bone erosion and new bone formation based on the CANDEN system and to describe patterns of inflammatory and structural lesions and their temporal development., Methods: 49 patients with axSpA from an investigator-initiated, randomised, placebo-controlled trial of adalimumab underwent spinal MRI at weeks 0/6/24/48. MR images were scored according to the CANDEN system and the Spondyloarthritis Research Consortium of Canada (SPARCC) method. Total scores, and various subscores, were created by summing individual lesion scores., Results: The CANDEN spine inflammation score had high responsiveness, similar to the SPARCC MRI spine index (Guyatt's responsiveness index 1.88 and 1.67, respectively), and discriminated between adalimumab and placebo treatment already at 6 weeks' follow-up (P=0.03). Anterior/posterior corner inflammation subscores showed similar responsiveness. Inter-reader reliability for the CANDEN spine inflammation and fat scores was good to very good for status and change scores (intraclass correlation coefficient (ICC)=0.71-0.92). Reliability for CANDEN new bone formation and erosion scores was good to very good for status scores (ICC=0.61-0.75) but, due to minimal progression, poor for change scores (ICC≤0.40)., Conclusions: The CANDEN spine inflammation score showed good responsiveness, discrimination between active treatment and placebo and reliability. The CANDEN spine structural scores had good cross-sectional reliability, but longer studies are needed to investigate their sensitivity to change., Trial Registration Number: NCT01029847; Results., Competing Interests: Competing interests: None declared.

Currently, there is little research investigating how schools can support the mental health and social development of young people with cystic fibrosis (CF), given their heightened risk of mental illness. Few studies have examined the relationship between bullying and mental health in populations of children with CF. This study describes the peer bullying experiences of young people with CF, and examines associations between school bullying and the psychological well-being of these young people. A sequential mixed-methods approach was used to collect data from 26 young people with CF (10-16 years of age). These data were compared with large samples of healthy children. Following an online survey, 11 young people, through online focus groups, expanded on the survey findings, describing their experiences within the school environment. Young people with CF reported lower involvement in bullying victimization and perpetration relative to the comparison population. For older adolescents with CF, victimization was associated with less connectedness to school and less peer support, and more school loneliness, anxiety, and depression. Young people with CF reported they generally liked the school environment, and were happy with their friendships, whereas some older adolescents reported that bullying evoked anxiety and mood problems. Reported bullying was primarily verbal and targeted characteristics of their CF, including their coughing, noninvolvement in certain activities because of shortness of breath, use of medication, and being underweight (for boys only). The findings provide some recommendations for interventions to promote mental health and school engagement among young people with CF.

Objective: To develop semiaxial magnetic resonance imaging (MRI) scoring methods for assessment of sacroiliac joint (SIJ) bone marrow edema (BME) in patients with axial spondyloarthritis, and to compare the reliability with equivalent semicoronal scoring methods., Methods: Two semiaxial SIJ MRI scoring methods were developed based on the principles of the semicoronal Berlin and Spondyloarthritis Research Consortium of Canada (SPARCC) methods. A global quadrant-based method was also developed. Baseline and 12-week MRI of the SIJ from 51 patients participating in a randomized double-blind placebo-controlled trial of adalimumab 40 mg every other week versus placebo were scored by the semiaxial and the corresponding semicoronal methods. Results were compared by linear regression analysis. The reproducibility and sensitivity were evaluated by intraclass correlation coefficients (ICC) and smallest detectable change [SDC, absolute values and percentage of the highest observed score (SDC-HOS)]., Results: Interreader and intrareader ICC were moderate to very high for semiaxial scoring methods (baseline 0.83-0.88 and 0.85-0.97; change 0.33-0.78), while high to very high for semicoronal scoring methods (baseline 0.90-0.92 and 0.93-0.97; change 0.77-0.89). Association between semiaxial and semicoronal scores were high for both the Berlin and SPARCC method (baseline: R 2 = 0.93 and 0.88; change: R 2 = 0.82 and 0.87, respectively), while lower for the global method (baseline: R 2 = 0.79; change: R 2 = 0.54). The SDC-HOS were 9.8-18.6% and 5.9-10.7% for the semiaxial and semicoronal methods, respectively., Conclusion: Detection of SIJ BME in the semiaxial scan plane is feasible and reproducible. However, a slightly lower reliability of all 3 semiaxial methods supports the general practice of using the coronal scan-plane in therapeutic studies.

Background: For decades, the most widely used imaging technique for myeloma bone lesions has been a whole-body skeletal X-ray survey (WBXR), but newer promising imaging techniques are evolving., Purpose: To compare WBXR with the advanced imaging techniques 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT), 18F-sodium fluoride (NaF) PET/CT and whole-body magnetic resonance imaging (WB-MRI) in the detection of myeloma bone lesions., Material and Methods: Fourteen patients with newly diagnosed multiple myeloma were prospectively enrolled. In addition to WBXR, all patients underwent FDG-PET/CT, NaF-PET/CT, and WB-MRI. Experienced specialists performed blinded readings based on predefined anatomical regions and diagnostic criteria., Results: In a region-based analysis, a two-sided ANOVA test showed that the extent of detected skeletal disease depends on the scanning technique ( P  < 0.0001). Tukey's multiple comparison test revealed that WB-MRI on average detects significantly more affected regions than WBXR ( P  < 0.005), FDG-PET/CT ( P  < 0.0001), and NaF-PET/CT ( P  < 0.05). In a patient-based analysis, a Cochran's Q test showed that there are no significant differences in the proportion of patients with bone disease detected by the different scanning techniques ( P  = 0.23). Determination of intrareader variability resulted in Kappa coefficients corresponding to moderate (FDG-PET/CT) and substantial agreement (WB-MRI, WBXR, NaF-PET/CT)., Conclusion: WB-MRI detects on average significantly more body regions indicative of myeloma bone disease compared to WBXR, FDG-PET/CT, and NaF-PET/CT. The lack of significance in the patient-based analysis is most likely due to the small number of study participants.

Objective: To investigate changes in magnetic resonance imaging (MRI)-assessed inflammation and structural lesions in the sacroiliac (SI) joints during treatment with adalimumab versus placebo., Methods: In a 48-week double-blind, placebo-controlled trial, 52 patients with spondyloarthritis were randomized to receive subcutaneous injections of either adalimumab 40 mg (n = 25) or placebo (n = 27) every other week for 12 weeks. Patients in the adalimumab group continued to receive and patients in the placebo group were switched to adalimumab 40 mg every other week for an additional 12 weeks. MRI of the SI joints was performed at weeks 0, 12, 24, and 48, and the images were assessed independently in a blinded manner using the modified Berlin and the Spondyloarthritis Research Consortium of Canada (SPARCC) MRI scores for inflammation and structural lesions of the SI joints., Results: At baseline, 56% of the adalimumab group and ∼72% of the placebo group had an MRI-assessed inflammation score of ≥1. Among the patients with inflammation at baseline, the mean percent reductions in MRI scores for inflammation from week 0 to 12 were greater in the adalimumab group compared with the placebo group (Berlin method, -62% versus -5%; SPARCC method, -58% versus -12% [both P < 0.04]). Furthermore, the mean SPARCC erosion score decreased (-0.6) and the SPARCC backfill score increased (+0.8) in the adalimumab group from week 0 to week 12. From week 12 to week 24, larger absolute reductions in the Berlin/SPARCC inflammation scores and the SPARCC erosion score and larger increases in the Berlin/SPARCC fatty lesion scores were seen in the placebo group compared with the adalimumab group. In univariate regression analyses (analysis of covariance) and multivariate stepwise regression analyses, treatment with adalimumab was independently associated with regression of the SPARCC erosion score from week 0 to 12 but not with changes in the other types of MRI lesions., Conclusion: Significant changes in the Berlin and SPARCC MRI-assessed inflammation scores and in the SPARCC MRI-assessed erosion scores occurred within 12 weeks after initiation of adalimumab. Tumor necrosis factor inhibitor treatment was associated with resolution of erosions and the development of backfill., (© 2016, American College of Rheumatology.)

Effective communication is a prerequisite to the delivery of good palliative care. The increasing use of web-based technologies and social media challenges us to reassess traditional communication styles and to define appropriate applications of evolving technologies. The use of Skype, blogging and webcams by patients in our hospitals and hospices is increasing. As illustrated in this case, the availability of such technology enables patients and families to communicate across wide geographical boundaries. This has particular advantages in situations where family members cannot routinely attend at the hospital because of other commitments or distance. The authors report on the varying use of Skype video-telephony over the course of a cancer patient's illness from the initial treatment phase through to the final days and hours of life. The benefits and challenges of using such technologies in a hospital setting and particularly in end-of-life circumstances are discussed.

In both the natriuretic peptide and renin-angiotensin systems, peptidases play an important role in the inactivation or activation of the system. Angiotensin-converting enzyme is responsible for the conversion of angiotensin I to angiotensin II, while neutral endopeptidase is one of the pathways involved in the degradation of the natriuretic peptides. The vasopeptidase inhibitors, which simultaneously inhibit neutral endopeptidase and angiotensin-converting enzyme, appear to offer distinct therapeutic advantages in treating hypertension, heart failure, and endothelial dysfunction.

S21402 is a vasopeptidase inhibitor that simultaneously inhibits neutral endopeptidase (NEP) and angiotensin-converting enzyme (ACE). This study determined whether chronic treatment with S21402 produced different effects on sodium and water excretion, hormonal parameters, and cardiovascular structure compared with selective inhibition of ACE and NEP in a rat model of myocardial infarction-induced congestive heart failure (CHF). CHF rats received the vasopeptidase inhibitor (S21402, 100 mg. kg(-1). d(-1)), an ACE inhibitor (captopril, 50 mg. kg(-1). d(-1)), a NEP inhibitor (SCH42495, 60 mg. kg(-1). d(-1)), or vehicle for 4 weeks. S21402 alone caused a diuresis and natriuresis (P<0.01) in CHF. After 4 weeks, blood pressure was lowered by captopril but not other treatments (P<0.01). Both S21402 and captopril increased plasma renin activity (P<0.01), all treatment lowered plasma aldosterone (P<0.05) and plasma natriuretic peptide levels were unchanged. In the kidney, S21402 inhibited NEP and ACE (P<0.01), SCH42495 inhibited NEP (P<0.01), and captopril inhibited ACE (P<0.01). Heart mass was reduced by all active treatments; captopril reduced left ventricular mass (P<0.01), SCH42495 reduced right ventricular mass (P<0.01), and S21402 decreased left (P<0.05) and right ventricular mass (P<0.01), atrial mass (P<0.05), and lung mass (P<0.01). In CHF, vasopeptidase inhibition with S21402 produces effects that differ from those of selective NEP or ACE inhibition. S21402 improved sodium and water excretion, reduced pulmonary congestion, and attenuated both right and left ventricular remodeling. These effects, which occurred in the absence of any hypotensive action, suggest that S21402 may offer several advantages over ACE inhibition alone in the treatment of heart failure.

The precise role of vasopressin in the pathophysiology of cardiovascular disease is controversial, but this peptide hormone is important for several reasons. Firstly, circulating concentrations of vasopressin are elevated in heart failure and some forms of hypertension. Secondly, there is evidence that vasopressin is synthesized not only in the hypophysial-pituitary axis but also in peripheral tissues including the heart where it acts as a paracrine hormone. Thirdly, vasopressin has vasoconstrictor, mitogenic, hyperplastic and renal fluid retaining properties which, by analogy with angiotensin II, may have deleterious effects when present in chronic excess. Finally, the availability of orally active non-peptide vasopressin receptor antagonists allows vasopressin receptor antagonism to be considered as a therapeutic option in cardiovascular disease.

Airbag injuries have resulted in the deaths of several infants and small children, and such deaths are generally associated with rearward-facing infant seats or unrestrained children in front passenger seats of cars equipped with airbags. An airbag can also cause death in a small child wearing a shoulder/lap belt, however, as this case report illustrates. A two-year-old female was involved in a low-speed collision while riding in the front passenger seat of a dual-airbag-equipped automobile. Secondary impact with the airbag caused catastrophic occipitoatlantoaxial disarticulation with traumatic spinal cord separation, thermal injury and abrasions of the right forearm and distinctive patterned abrasions of the face. The possibility of airbag injury should be considered in all low-speed traffic fatalities, and the confirmatory injuries sought at postmortem examination.

The investigation of the deaths of an elderly couple found in a small hotel room that was tightly sealed and heated by an open flame gas heater is presented. Autopsy and toxicologic studies did not reveal a definitive cause of death. Subsequent research and an experiment to duplicate the conditions support the contention that the cause of death was hypoxia due to oxygen depletion by the gas flame.

Embolization is a well-recognized phenomenon in medicine and forensic pathology and generally involves formed blood elements, bone, air, amniotic fluid, or more exotic items such as bullets. We report the embolization of a chain-saw link. The case demonstrates how, without complete autopsy and investigation, a penetrating sharp-force injury could be misdiagnosed and a false conclusion as to the commission of a crime could occur. Although the forensic literature is replete with examples of bizarre emboli, from bullets to suspected crystals of methylmethacrylate, a literature review failed to find a single case of penetrating chain-saw-link injury as a cause of traumatic death. Most reports of chain-saw incidents cite accidental injuries to hands and arms or dramatic facial injuries due to entrapment and recoil (1,2). One fatality occurred from a skull fracture and cerebral injury when a 19-year-old man fell onto a saw.

This paper presents a brief review of the results of research in the area of electrical skin injuries. It also includes a case report of a 5-year-old girl noted on her admission to the hospital to have injuries to the skin of her chest and left arm. Histological examinations demonstrated that the skin lesions were segmental and showed necrosis and inflammation. Deposits of calcium salts distinctly located to collagen fibers were observed below the regenerated epidermis at the periphery of two skin lesions of the chest wall, in the lower part of dermis at the periphery of a skin lesion of the left arm, and within connective tissue adjacent to elastic arteries and peripheral nerves from the thoracic cavity. The pattern of calcification localized to collagen fibers and situated both superficially and deeply in the skin in a zone of viable tissue close to necrotic tissue is characteristic of electrically induced lesions. Although there have been reports of deposition of calcium salts on collagen fibers after application of calcium salts in high concentration at the skin surface, the collagen calcification in the pattern observed in this patient is probably diagnostic of electrical injury.
